Answer:

12 and 13

Step-by-step explanation:

let the consecutive numbers be n and n + 1 , then their difference is

(n + 1)² - n² = 25 ← expand parenthesis on left side using FOIL

n² + 2n + 1 - n² = 25

2n + 1 = 25 ( subtract 1 from both sides )

2n = 24 ( divide both sides by 2 )

n = 12 and n + 1 = 12 + 1 = 13

the 2 numbers are 12 and 13 , that is

13² - 12² = 169 - 144 = 25

Answer:

-3/2

Step-by-step explanation:

The slope of a line is calculated by dividing the difference in the y-coordinates by the difference in the x-coordinates.

Here, the given ordered pairs are (-6, -8) and (-14, 4), so the slope is:

slope = m = (4 - (-8)) / (-14 - (-6)) = 12 / (-8) = -3/2

The answer is thus -3/2.

The solution to the equation x - 3[(2/3)x + 3] = [(-3/2)x + 1 - (3/2)x gives the value x = -4

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation:

x - 3[(2/3)x + 3] = [(-3/2)x + 1 - (3/2)x

x - 2x + 9 = [(-3/2)x + 1 - (3/2)x

Multiplying through by 2:

2x - 4x + 18 = -3x + 2 - 3x

Adding like terms:

-2x + 18 = -6x + 2

-4x = 16

x = -4

The solution to the equation x - 3[(2/3)x + 3] = [(-3/2)x + 1 - (3/2)x gives the value x = -4

Answer:175ft cube is the volume of the figure.

Step-by-step explanation:The volume of lower part is,

V=L*B*H

V=5*7*2

V=70ft cube

Volume of upper grade part is,

V2=L*B*H

V2=3*5*7

V2=105ft cube

Therefore total volume=V+V2

=175 ft cube

Answer:

a. The area of the square is 25 feet x 25 feet = 625 square feet.

b. To find the percent of points that landed in the pond, we divide the number of points that landed in the pond by the total number of points generated and multiply by 100.

3,200 points / 5,000 points = 0.64

0.64 x 100 = 64%

so 64% of the points landed in the pond.

c. To find the area of the pond, we multiply the proportion of points that landed in the pond by the area of the square.

64% of the points landed in the pond = 0.64

Area of the pond = 0.64 x 625 square feet = 400 square feet. So, the area of the pond, to the nearest square foot, is 400 square feet.

The appropriate test statistic for comparing the number of students who met or did not meet a cutoff score on two different days would be the McNamar's test.

McNamar's test is a statistical test used to compare paired proportions or counts of dichotomous data.

In this case, the paired proportions would be the number of students who met or did not meet the cutoff score on day 1 and day 2.

The test statistic for McNamar's test is the chi-square statistic, calculated using the following formula,

X² = ((b-c)²) / (b + c)

where b is the number of students who met the cutoff score on day 1 but not day 2,

And c is the number of students who did not meet the cutoff score on day 1 but did meet the cutoff score on day 2.

The chi-square statistic follows a chi-square distribution with 1 degree of freedom.

A p-value can be calculated based on this distribution to determine if there is a statistically significant difference between the paired proportions.

Step-by-step explanation:

The equation of the ellipse centered at the origin, satisfying the given conditions, is:   \(x^2/25 + y^2/29 = 1.\)

To write an equation of an ellipse centered at the origin, we can use the standard form equation:

\(x^2/a^2 + y^2/b^2 = 1\)

where "a" represents the semi-major axis and "b" represents the semi-minor axis.

Given that the vertex is located at (0, √29), we can determine the value of "b". The distance from the origin to the vertex is equal to the value of "b". In this case, √29 is the value of "b".

Now, we need to determine the value of "a". The co-vertex is located at (-5, 0). The distance from the origin to the co-vertex is equal to the value of "a". In this case, 5 is the value of "a".

Plugging these values into the equation, we get:

\(x^2/5^2 + y^2/√29^2 = 1\)

Simplifying, we have:

\(x^2/25 + y^2/29 = 1\)

Independent events- events that do not affect each other's probability of occurring. Dependent events- events where the occurrence of one event affects the probability of the other event happening. Mutually exclusive events- events that cannot occur at the same time. Exhaustive events- events that cover all possible outcomes.


1. Independent events: Independent events are events in which the occurrence of one event does not affect the probability of the occurrence of another event. In other words, the outcome of one event has no impact on the outcome of the other event.

2. Dependent events: Dependent events are events in which the occurrence of one event does affect the probability of the occurrence of another event. The outcome of one event is influenced by the outcome of the other event.

3. Mutually exclusive events: Mutually exclusive events are events that cannot occur at the same time. The occurrence of one event means the other event cannot occur. For example, flipping a coin and getting both heads and tails at the same time is a mutually exclusive event, as it is impossible for both to happen simultaneously.

4. Exhaustive events: Exhaustive events are a set of events that include all possible outcomes in a given situation. They are complete and cover every possibility, leaving no room for additional outcomes. For example, when flipping a coin, the set of exhaustive events includes both heads and tails, as there are no other possible outcomes.

The median of 14 is the most accurate to use, since the data is skewed.

The most appropriate measure of center to represent the data depends on the nature of the data distribution. Looking at the histogram provided, it appears that the data is positively skewed, with a long tail towards the right. This means that there are a few larger values (donations in this case) that are pulling the mean towards the right, while the median is a better representative of the typical or central donation.

Therefore, in this case, the median of 14 is the most accurate measure of center to use to represent the data, since it is less affected by the extreme values and gives a better idea of the central tendency of the data. The mean of 13.2 is also close to the median and can be used as a measure of center, but it is not as representative of the typical donation due to the skewness of the data.

The median of 13.2 and the mean of 14 cannot be used to show whether the charity needs more or plenty of money, as this depends on other factors such as the expenses and goals of the charity.

Given tan(x)=24/25 (in quadrant 1), the value of sin(2x) is 2352 / 15625.

It should be noted that tan(x) = sin(x) / cos(x)

Given tan(x) = 24/25, we can represent it as:

24/25 = sin(x) / cos(x)

cos²(x) + sin²(x) = 1

Since we're in quadrant 1, both sin(x) and cos(x) are positive. Let's solve for cos(x):

cos²(x) + (24/25)² = 1

cos²(x) + 576/625 = 1

cos²(x) = 1 - 576/625

cos²(x) = 49/625

Taking the square root of both sides:

cos(x) = sqrt(49/625)

cos(x) = 7/25

Now that we have cos(x), we can find sin(x) using the given equation:

24/25 = sin(x) / (7/25)

Multiplying both sides by (7/25):

(7/25) * (24/25) = sin(x)

168/625 = sin(x)

Now, we have sin(x) and cos(x), and we can use double angle formula to find sin(2x):

sin(2x) = 2 * sin(x) * cos(x)

Substituting the values we found:

sin(2x) = 2 * (168/625) * (7/25)

sin(2x) = (2 * 168 * 7) / (625 * 25)

sin(2x) = 2352 / 15625

Therefore, sin(2x) = 2352/15625.

Answer:

88% is the correct answer

22, divided by, 25, end fraction of a number is 88% of that number.

To find what percentage 22, divided by 25, is of a number, we can set up an expression using the formula for calculating percentages:

Percentage = (Part / Whole) * 100

Where:

Part is 22 divided by 25 (22/25).

Whole is the original number.

Let's represent the original number as "x":

Percentage = (22/25) / x * 100

Now, let's find the percentage value.

To do that, we need to divide 22 by 25 and then multiply by 100:

Percentage = (22/25) * 100

To simplify, you can cancel out common factors in the fraction 22/25:

Percentage = (22 * 4) / (25 * 4) * 100

Percentage = 88 / 100 * 100

Now, multiply the fraction by 100 to get the percentage:

Percentage = 88%

So, 22, divided by 25, is 88% of the original number.

The number of miles in a day at which the rental costs for Company A and Company B are the same will be 200 miles.

We are given that:

For Company A:

Fixed cost = $ 110

Variable cost = $ 0.20 per mile

For Company B:

Fixed cost = $ 70

Variables cost = $ 0.40 per mile

Let the number of miles in a day be x.

So, the equation for rental cost for company A will be:

Rental cost = 110 + 0.20 x

The equation for rental cost for company B will be:

rental cost = 70 + 0.40 x

Now, put both rental cost equal.

110 + 0.20 x = 70 + 0.40 x

0.40 x - 0.20 x = 110 - 70

0.20 x = 40
